How to write to DDR of a DE1-SoC using the ARM processor?

I have some input data I want to copy to the DDR memory. This data is loaded once and it's never changed. I know I can load this data using the FPGA (as seen here), but I'm looking for an alternative...

Hi!

I'm using Quartus Prime Standard 18.1 for Windows.

Hi,

I could not find any further information regarding the error itself, have you tried booting up your board to see if the DDR is up from preloader?

Here is the get_editable_mem_instances descriptions for reference:

You may check all other functions available here:
